The Rhine and its tributaries have cut deep valleys into the high plateau of the Hunsrück in the Bacharach area, on the slopes of which slate occurs, which was used in construction and especially for roofing. You are standing here in front of an old slate tunnel.

There are several slate mines around Steeg where mining continued until the 20th century. The mines are closed with steel bars for safety reasons.
